The ADG1419 is a monolithic 2.1Ω switch with a 0.5Ω maximum on resistance flatness at 25°C, fully specified at +12V, ±15V, ±5V, no VL supply required, 3V logic-compatible inputs, and support 8-lead MSOP and 8-lead 3mm×2mm LFCSP packages.
The ADG1419 is a monolithic iCMOS device that provides a single‑pole/double‑throw (SPDT) switch. It features a typical on‑resistance of 2.1 Ω, flat resistance across the analog range, and up to 390 mA continuous current per channel. The switch operates with 3 V logic‑compatible inputs and requires no separate logic supply, supporting dual‑supply (+15 V/+5 V) and single‑supply (+12 V) configurations.
Typical applications include automatic test equipment, data‑acquisition systems, battery‑powered instruments, relay replacements, and signal routing for audio, video, and communication systems. The device is offered in 8‑lead MSOP and 8‑lead 3 mm × 2 mm LFCSP packages.

The typical on‑resistance is 2.1 Ω at 25 °C.
It can be powered from dual supplies of ±15 V, ±12 V, or ±5 V, as well as a single +12 V supply.
The high‑level input threshold is 2.0 V minimum and the low‑level threshold is 0.8 V maximum.
Each channel can handle up to 390 mA of continuous current.
